Btw, i do not mean that all Android apps just look great. They still have to be coded properly for multiple resolutions, its just that the API allows that to be done for any resolution if the dev puts the effort in.
Where as apple apps still need patching with updates from XCode if new OS' come out with different resolutions.
That's not true. I have some apps that are optimised for the iPhone 5 but run fine on my ipad mini. I think a downside is that many apps you have to purchase twice, a version for the iPhone/iPod and another for the iPad.
If you have to buy it twice it means its not universal, and the dev has had to make a custom version for it.
